[Austin6132]

I own a farm pro 2425 y385 the rear 3 pt wont lift and when I detached the loader hydraulics it completely stalled out and now it wont start without the loader hydraulics connected idk how this thing works I work on tractors for a livening but I’m lost. any suggestions or anything that could possibly be wrong with it? Not leaking fluid or anything

How many lines do you have to disconnect when removing the loader? 3 or 4? If 3, then two of those will need to be connected back together.

So don't insist on starting the tractor like that, or you'll damage the hydraulic pump.

Basically when removing the loader, does the valve stay connected to the tractor?
Or does the loader valve go with the disconnected loader frame?

IF the valve goes with the loader frame, the P and PB hoses will need reconnected for the 3PH to work and not deadhead the pump.

I wonder if OP tried your advice, and how it worked for them.

there’s only 2 hoses a pressure and return

 

[Billrog]

Connect them or like posted the pump will be damaged.

 

[ptsg]

Ok, so those two hoses must be connected to each other.

I found a manual for a Jinma 254, which I believe is very similar to the Farm Pro 2425. There is a section where it explains the front loader and how the hoses must be connected. Hopefully it helps you understanding a bit better. Just scroll down to page 20: https://www.kenotractors.com/wp-content/uploads/2017/09/JINMA200Series-2016.pdf

Need a loop back hose to connect the two connectors to each other otherwise hydraulic pump is deadheading against the blockage cause by quick connect... If you continue trying to run tractor with out loop back hose it will possibly destroy the pump....

 

[LD1]

Yup. Open center tractor......with the loader hooked up is like looping those two hoses together.

So with loader removed....and the valve no longer connecting those hoses.....you need to couple them back together yourself

 

[Farmer495]

Agree with connecting the two hoses together.

IF the loader was properly plumbed with quick connects on the loader valve, you should have had a male and female hose to connect together.

I remove loader from tractor here that the valve stays with loader, I have to connect the hoses together with the factory set up quick connects.

so I connected the two and it started just fine and I found the manual in my dads office but now the valve adjustment know or deal thingy won’t turn like at all I beat the thing a hammer to a vice grip to it used pipe wrenches and regular wrenches nothing it’s like it’s seized I tried it with it off and on with it connected to the loader and disconnected from the loader made sure the three point arm lever was in neutral or off however you wanna say that and the three point arms are just limp like u can lift them by hand and they drop like a bag of rocks there’s no pressure behind them when u lift or when u drop

 

[ptsg]

Where is that valve located? Is that near the two hoses for the loader than you connected back?

 

[Austin6132]

The pump or valve is located under the seat and the valve adjustment deal is right in front of the seat. The proper name is hydraulic power lift is what the owners manual calls it but it wont turn at all

 

[Austin6132]

The loader had just had two hoses that ran to the tractor with quick connects and the lever and **** all went with the loader

 

[Xfaxman]

and the three point arms are just limp like u can lift them by hand and they drop like a bag of rocks there’s no pressure behind them when u lift or when u drop

That is normal for most tractors.
There is no down pressure, so the arms are free to go up and back down to where they were lowered to.

I get that but they don’t work at all

Did the 3 point work before you disconnected the loader?

 

[Austin6132]

It used to work and then my dad and his friends messed with the dials to get the loader working better now nothing for the 3 point
